Abstract: A system and apparatus for producing seasoned food products where seasoning is performed at individual packaging lines.  The product is conveyed from the preparation area to a packaging area in an unseasoned condition. Upon reaching the packaging lines, which are disposed in packaging departments in the packaging area, the product can be selectively seasoned independent of other packaging lines.  After seasoning, the product is packaged and prepared for delivery.  At each packaging line, a volumetric feeder includes a feed head that cooperate with a tumbler having helical flights to produce continuous controlled product portions.  A seasoning dispenser is positionable within the tumbler and can be adjusted to dispense a given weight of seasoning at a given rate, based on the amount of product passing through the tumbler, to obtain consistent seasoning levels and coverage.  The ability to produce separate product types at each packaging line yields superior plant scheduling flexibility due to more packaging possibilities than a system which delivers already seasoned product to the packaging lines.     ,   .    .    .

Title: Piezoresistive pressure transucer circuitry accommodating transducer variability
Inventor: COWAN MARK W
IPC: G01L19/04
Filed: 1998-01-07
Abstract: Pressure transducer circuitry accommodating pressure transducer variables for making pressure measurements in a living body.  A microminiature piezoresistive pressure transducer has first and second variable resistive elements.  The pressure transducer is characterized as having a pressure sensitivity ranging from 1.2 to 15 ohms per 1,000 ohms per 100 millimeters of mercury and a temperature characteristic greater than pressure sensitivity. Circuitry is coupled to the first and second variable resistive elements of the transducer including a known fixed resistive element.  The known fixed resistive element is coupled to the first and second variable resistive elements for supplying a transducer excitation voltage through the known fixed resistive element to the first and second variable resistive elements.  First and second amplifiers each having an input and an output are provided.  The inputs of the first and second amplifiers are connected to the first and second variable resistive elements to measure the voltage across the first and second variable resistive elements so that the first and second amplifiers have outputs which have a pressure component and a temperature component therein. A computer receives the outputs of the first and second amplifiers and ascertains the unknown resistances of the first and second variable resistive elements as independent variable resistive elements by solving a set of equations having said first and second variable resistive elements as unknowns and pressure and temperature as the remaining unknowns to provide a temperature compensated pressure value as measured by the microminiature pressure transducer.

Title: Employing customer premises equipment in communications network maintenance
Inventor: BOWKER DUANE OLIVER
IPC: H04M3/40
Filed: 1998-03-19
Abstract: The present invention customizes a network connection to customer premises equipment using a calibration signal. A network signal processor emits a tag signal indicating that a signal processing plafform is in use. Customer premises equipment (CPE) issues a calibration signal to the network signal processor based on detection of the tag signal. The customer premises equipment outputs the calibration signal to the network signal processor which measures the signal loss, adjusts the gain mapping and issues a calibration signal to the customer premises equipment. The customer premises equipment then estimates spectral shaping based on the calibration signal from the network signal processor and equalizes the receive path so that the signal processing platform is detected and implemented. Embodiments of the present invention are illustrative of a more general concept of the use of CPE as an agent in telephone network maintenance.
